SFECFICATION forming part of Letters Patent No. 387,880, dated .August 14, 1888.

Application filed March Q9. 1888. Serial No. 268,734. (No model.)

To all whom it may concern:

Bc it known that I, JOHN G. HODGSON, a citizen ol' the United States, residing in Maywood, in the county of Cook and State of Illinois, have invented a nev.1 and useful Improvement in Can-Heading Machines, of which the following is a specification.

My invention relates to machines for automatically applying the heads or ends to sheetmctal can-bodies.

My invention consists in the combination, with a mold or device for holding the fcanbody, a piston or device for forcing the canhead upon the can-body7 and a can-head-supu ply chute through the mouth or base of which said piston reciprocates, of a movable stop or support for holdingor supporting the canheads in the supply-chute, so that but a single head may iced down at a time in front of the piston at the mouth of the mold, and mech- :mism for operating said movable stop to release the can-heads in said chute when the piston makes its forward stroke and to arrest or support the can-heads when the piston makes its backward stroke, said piston supporting the can-heads when the same are released by said stop, whereby two or more canhcads are prevented from slipping down at a time between said cairbodyholding device and said piston. By this means the machine is made to operate more perfectly and stoppages and delays are prevented.

Any suitable means may be employed for operati-ing the movable support or stop at proper intervals. I prefer to operate it by means of a lever which is engaged by a projection on the piston or its slide.

My invention further consists in a mold or device for holding the canbody, furnished with sliding interior sleeves or sections which are pushed in endwise as the canhead is forced upon the can bythe piston. These sli p sleeves I also furnish with an annular channel to receive the iiangc of the can-head, and thus guide the same over the can-bod y as the sleeves are pushed in.

My invention further consists of a can-bodyclamping device made in two parts which separate from each other, in combination with movable lingers or supports to hold or snpport the can-body While the mold or clamping device is closing ngen the saine. These canhody supports or lingers are retracted,so as to discharge the headed can, when the clamping device opens.

My invention also consists in the novel devices and novel combinations of parts or devices herein shown and described, and more particularly pointed out in the claims.

In the accompanying drawings, which form 6o deviee,shovving the can-bodyi`eed ch lite. Fig. 6 is a cross-section on line G G of Fig. 5, showing the device for feeding the can-bodies one Fig. 5 7 1s a cross-section of the canbody-clamping Fig. 3 is a detail hori- 65 by one to the can-body-holding device; and 7 5 Fig. 7 is a detail view of the can head-supply chute.

In said drawings7 A represents the frame of the machine; B B, the two parts of the canbody clamping or holding device; O O, the so pistons for applying the heads to the can-body; D D, the can-headed ppl y chutes, th rough which the can-heads are fed down in iront oi" the pistons C, and F is the can-body-supply chute,

through which the canbodies are fed to the can-holding device.

The can-body-holding device B Il is preferably made in two parts, both of which are movable. As shown in the drawings, they are both made to reciprocate and are attached 9o to and operated by suitable slides, B', which move in guideways B2 on the frame, and are operated by suitable cams, B Bl. The two.- part can-body-holding device B is preferably made in the form of half-cylinders, which are each furnished with sliding interior sleeves or sections, @which conform to the cireumference of the ean-body. These sections b are furnished with an annular channel or groove, b', at their ends to receive the flaring roo edge of the can-head flange The sliding sections t have hanged inner ends, @which tit in an annular recess, b3, in the part B. The Width of this recess b3 is sufficient to permit the sliding sleeves Z1 b to approach each other far enough to allow the heads :c to be forced upon the can-body w' to the full depth of the anges of the heads. The sliding interior sleeves, b, are secured in the half-molds B B, so that they may slide thereon, by means of screws b, which are threaded into the sleeve b, and the heads of which lit in longitudinal slots b5, cut in the half-molds B. The sliding sleeves b on the half-molds B are forced apart by light springs b. The flanges b2 on the sleeves B limit the outward movement of the sleeves, so that the outer ends of the sleeves will just be flush with the end of the can-body inside the mold.

The pistons C for applying the heads to the can-bodies are furnished with one or morepreferably three-projections or anges, c, to receive and guide or center the can-head in respect to the can-body held in the clamping device B. One of these flanges c is located at the lowermost part of the piston-head and the other two at the extremities of the horizontal diameter, so that the heads may drop down upon these supporting-flanges from the feed-chute D. In cases where, as shown in the drawings, these can-head guiding and supporting projections or flanges c are used in combination with the particular construction of can-body-holding device heretofore described, or a can-body-holding device having sliding sleeves or sections b, I provide these projections c preferably with square ends, which bear against the sliding sleeves b, and thus serve to force or push the sleeves in as the piston advances, and thus relieve the flange of the can-head from the strain necessary to overcome the force of the springs b. The pistons C are attached to slides G', which move in guideways C2 on the frame of the machine. They are operated by cams C3 0*.

The can-head-supply chute D is furnished with a movable stop or support, d, which operates to hold or support all the can-heads in the chute except the last one, which is permitted to drop down in front of the piston when the piston is withdrawn. Thismovable support d for the can-heads maybe automatically and very conveniently operated or withdrawn, so as to permit the can-heads to feed down on top of the piston by means 'of a projection, d', on the piston or its slideway, which strikes against an adjustable pin, d2, attached to the lever d3, upon the upper end of which thesupport d is mounted. The lever d is pivoted at d* to the frame of the machine. A spring, d5, serves to hold the movable support d in position to support the can-heads, except when the same is retracted bythe forward movement of the piston C.

When the piston C moves forward to force the can-head upon the can-body, the projection d will operate the lever d and withdraw the stop or support d, so that all the can-heads in the chute resting one ou top of another may press down upon the piston C. The moment the piston begins to recede,however,the spring d5 will operate the lever d and project the pin d through the slot d6 in the can-head chute, so that the end of the pin d will engage or press against the second can-head in the chute, and thus support the same and all the can-heads above it, while the lowermost can-headin the chute will be free,and alone free,to drop down in front ofthe piston when the piston is sufficiently retracted to permit it to do so. The pin or support d is adjustable in the lever d3 by means of the set-screw, and the height of the lever itself is adjustable, so that this feed device may be adapted to can-heads of different diameters or sizes.

After the heads have been applied to the can-body by the pistons C, the parts B B of the can-body clamping or holding device separate or are retracted to permit the headed canbody to be discharged and a second can-body from the chute F to feed in between them. To properly support the next succeeding canbody while the part molds B B are open, I

provide the part molds with a movable canbody-holding finger, G, preferably secured to a sliding pin, g, extending through a suitable opening in the mold B or the slide to which it is attached. This sliding pin g is provided with a recess, g', in which fitsaspring-pin, g2. The pin g2 has a head, g, whichengages a stationary cam, g, secured to the frame of the machine or to the slideway B?. A spring, g5, serves to extend or move the rod g, so that the finger G will be in position for supporting the can-body when the holding-pin g2 is retracted by the cam g Now, when the mold B begins to recede or open,the pin g2, engaging the rod g, will cause the nger G to be retracted with the mold B until the molds and ngers are sufficiently opened or separated to permit the headed can to be discharged. The instant, however, the headed can is discharged from the mold, and before thc next succeeding can can fall down between the molds B B from the chute F, the head of the pin g? will have engaged the cam g4, and thus released the rod g, so that the spring gi will extend the finger G into position to catch and support the next succeeding can as it falls, and so hold it until the molds B B close upon the same. As the molds B B close together, the fingers G G will be retracted within the moldsinto position for the spring-pin g2 to engage the recess g in the rod g. By this means,therefore, the can-bodies will be automatically fed. from'the deliverychute into the mold and be discharged therefrom after they are headed.

[t will be observed that I have described and shown my invention as adapted to simultaneously apply the heads to the opposite ends of the can-body. The devices at the two ends, however, are merely duplicates of each other, and in cases where it isonly desired to apply a head to one end of the can-body the devices at the other eud need not be used, or may be omitted entirely from the machine.

l{Vhilc the sliding section or sleeve b, which serves to guide the rlange of the can-head upon the can-body, is shown in the drawings as a continuous sleeve, it will of course be understood that this guide-section b need not be a continuous sleeve entirely encircling the canbody, but may be in parts cut away and only engage the ilange ofthe can-head at a portion instead of the whole of its circumference. It should also be understood that my invention is equally applicable to operating upon other than cylindrical cans, the cau-body-holding device and pistons being, of course7` made to correspond to the shape of the can.

in order to properly feed or deliver the canliodies one by one from the chuteF to the caubody-holding device B, I provide the chute F with a inovabie stop, H, which operates automatically to discharge the cans one by one. This movable stop or feed lever is pivoted to the frame and is operated by a short arm, 7i, through the pivoted link i,cani h2, and spring Il. llie com serves to intermittently raise the lever il out ol' the path of the can-bodies in the chute Rand thus perrnit one can to roll past the lever, when the gate or lever H again descends and holds thereniaining cans,the movement boing properly timed in relation to the movements ofthe molds B B and pistons G C.

The can head-supply chute D is furnished with slots 7F to permit the projections c of the pistou G to pass through said chute. In case the sliding sleeve or section b of the can-body holder B were omitted, theholder B should be provided with similar notches to receive the projections c of the ean-head-applying pistou.
